How do we call when the plant contains two different kinds of leaves?

Explanation

1. Occurrence of two different kinds of leaves in the same plant is called heterophylly.
2. It is found in many aquatic plants. Here, the floating or aerial leaves and the submerged leaves are of different kinds.
3. Heterophylly in water plants is, thus, an adaptation to two different conditions of the environment. Eg: Limnophila heterophylla.
